port forward not working on port 25565

There could be several reasons why your Minecraft server port is still closed even after you have port forwarded and allowed the ports through your firewall:

Double check your port forwarding settings: Ensure that you have correctly set up port forwarding on your router. Double check that you have forwarded port 25565 to your server's local IP address.

Check your firewall settings: Make sure that your firewall is allowing inbound and outbound connections for port 25565.

ISP blocking the port: Some ISPs block certain ports for security reasons. Check with your internet service provider to make sure that they are not blocking port 25565.

Router blocking the port: Some routers may have a built-in security feature that blocks incoming traffic on certain ports. Check your router's settings to see if it is blocking port 25565.

Incorrect IP address: Make sure that you are providing your friends with the correct IP address to connect to your server. You can find your public IP address by doing a quick search on Google for "What is my IP address".

Minecraft server software settings: Double-check that the Minecraft server software is configured correctly to use the correct port.
